The motor size on the GTR depends on which series you have:

🔌 GTR Series 1

• Equipped with 2 x 1500W motors (each)

• Uses a motor controller specifically tuned for 1500W motors

⚡ GTR Series 2

• Equipped with 2 x 3000W motors (each)

• Delivers more torque and improved hill-climbing

• Uses a different motor controller designed for higher output

❗ Important compatibility notes

• GTR Series 1 cannot run 3000W motors

• GTR Series 2 cannot run 1500W motors

The motors and motor controllers are matched as a system. Swapping motor sizes between Series 1 and Series 2 is not supported and will result in improper operation.

⚙️ What about gears?

Both GTR Series 1 and Series 2 support the same range of gearing options, regardless of motor size:

• 32T

• 38T

• 47T (when available)

• 66T

There is no specific motor required for a specific gear. Gear choice affects ride characteristics like speed, torque, and acceleration, but does not determine motor compatibility.

✅ Key takeaway

• Series 1 = 1500W motors only

• Series 2 = 3000W motors only

• Gear choice is flexible across both series
